FAN ATTACHMENT FOR AUTOMOBILES.

Application filed January 31, 1927. Serial No. 164,920.

part of acombined heating and ventilating means.

One object of the invention is to provide anew and improved fanv whosecasing is provided with novel means for mounting it upon theconventional automobile motor, provision being made whereby the casingmay be properly positioned to effectively engage a driving ulley of thefan with the usual fan belt of the motor.

Yet anotheraim is to provide an attachment for automobiles, which will.be rather simple and inexpensive, yet will be efficient, reliable and in'every way desirable. With the foregoing in view, the invention residesin the novel subject matter hereinafter described and claimed, thedescription being supplemented bythe accompanying drawings. v

Fig. 1 is an elevation partly in section, showing the application of'theinvention to an automobile rather diagrammatically.

Fig. 2 is a top plan view of the parts shown in Fig. 1.

Figs. 3 and 4 are respectively a front elevation and a rear elevation ofthe fan, each view being partly in section.

Fig. 5 is a top plan view of the fan. 1

Fig. 6 is a central vertical longitudinal section on line 6-6 of Fig. 5.

The construction selected for illustration in the present applicationwill be rather specifically described, with the understanding however.that within the scopeof the invention as claimed, variations may bemade. Y

The fan embodies a fan proper F and a casing C. This casing embodies acylindrical side wall 7 having a laterally projecting discharge neck 8and provided wlth upper' and lower bosses 9 and 10 in which verticallyalined-studs 11 are threaded, said studs being provided with nuts .12 bymeans of which they may be secured to upper and lower brackets orsupports 13 and 13. In,- tegral with the side wall 7, is a front endwall 14 which is provided with an air inlet elbow 15 integrally joinedthereto, and is equipped also with a central, shaft bearing 16. Theelbow 15 is provided with a suitable air filter or-screen 17.

' Therear end wall 18 of the casin G is provided with a central, shaftbearmg- 19 and with a boss 20 in which a threaded stud 21 is anchored,said stud being at an angle to the common axis ofthe studs 11 and beingprovided. with a nut 22, whereby it may be secured to a third bracket orstrap 23. This rear wall 18 is removably secured to the side wall 7, bya plurality of machine screws 24.

The shaft 25 of the fan F is rotatably received in the bearings 16 and19 and projects forwardly from the elbow 15, the forwardly projectingportion being provided with a flanged driving pulley 26.

The fan is attached to-the automobile motor in a manner which will beclear from Figs. .1 and 2. The bracket 13 is anchored by means of one ofthe cylinder head bolts B, the bracket 13 is anchored by one of theusual crank case bolts B, and the bracket 23 is secured to the motor byone of the bolts B which connect the water return pipe P with the enginejacket. When the fan is mounted in this manner, its pulley 26 ispositioned to engage the usual belt I) of the automobile fan f. Wheninstalling the device, the two vertically alined studs 11 which passturnably through openings 27 in the brackets 13 and 13, permit turningof the fan casing about a vertical axis to properly position the pulley26 for cooperation with the belt I). Then, by securing the third bracket23,

the casing is effectively held against further turning about theaforesaid axis.

An air conducting pipe 28 has been shown extendin rearwardly from theair discharge neck 8, t 1e front end of said pipe merely fit- I tinginto an opening 29 in the rear side of said neck. This pipe ispreferably,'althou'gh not necessarily formed from thin sheet metal. Abranch 30 is shown rising from the pipe 28'to a suitable register 31which may well be positioned under the front portion of the frontautomobile seat, and a similar arrange. ment may be rovided inconnection with the rear seat. T us, any current of air which ispermitted to flow rearwardly throughout thelength of the pipe 28, willdischarge through the registers 31 to effectively vent-ilate thecar-body. Provision is made however, whereby the air maybe shunted fromthe pipe 28 and heated before it is discharged into the body.

32 designates an air heating jacket sur-' rounding a from the motor.Front and rear caps 33 and 34 are provided for this jacket, and aportion of the exhaust pipe E I ed with an appropriate register 36disposed in the floor-boards or at other desired loca-v tion. Mypreference, the jacket 32 is flexible to realtliily adapt itself to thecurvature of the 1 e p it suitable valve 37 is provided at the junctureof the pipe 28 with the branch35, and by means'of an appropriate control38 runnlng to a point within reach of the driver, this valve may bemoved to either of two positions. When the valve is in one position, thecool air from the fan F may pass rearwardly through the piping 28 fordischarge through the registers 31 to ventilate the car. However, whenthe valve is in its other position, the piping 28 is obstructed directlybehind the branch 35, forcing the air from the fan to pass through thisbranch into the air heating a cket 32. In this jacket, the air iseffectively heated by contact with the exhaust pipe E, and the heatedair dis-.

charges into the car body through the register 36.

' Excellent results are obtainable from the general construction andarrangement shown and described, such construction and arrangement beingtherefore preferably followed. However, within the scope of theinvention as claimed, variations may be made.

I claim:

1. In an air supply device for a motor vehicle body; a fan having acasing and a belt pulley inffront thereof for contact with theconventional fan'belt, upper and lower attaching brackets contactingwith the upper and lower sides of said casing and having verticallyalined openings, vertically alined threaded fasteners passing rotatablythrough said openings and connected with the easing, said fastenerspermitting turning of the casmg about the common vertical axis of saidfasteners when the latter are loosened, andan additional attachingbracket connected with the casing at a point laterally oflset fromsaid-axis, said brackets being adapted for attachment to the automobilemotor, said additional bracket then holding the casing against turningabout said axis.

2. In an air supply device for a motor vehicle body; a fan casingcomprising a cylindrical side wall having upper and lower verticallyalined threaded studs for connection to attaching brackets and providedalso with an integral lateral discharge neck, a front wall integral withsaid side wall and having an integral air inlet elbow and a centralshaft bearing, and a rear wall detachably secured to said side wallandhavin a central shaft bearing, said rear wall being pro- 4 vided alsowith a threaded stud whose axis is at an angle to the common axis ofsaid vertically alined studs.

In testimony whereof I have hereunto aifixed my signature.
